WIRE TWISTER.

Application filed. December 11,1922. Serial No. 606,095.

T all whom it may concern:

Be it known that 1, Jason H. GREEN- srnnnr, a citizen of the UnitedStates, residing at Indianapolis, in the county of Marion and State ofIndiana, have invented a new and usefullVire Twister, of which thefollowing is a specification.

The object of my invention is to produce an efficient device by means ofwhich two ends of wire may be twisted together in substantialparallelism. The device is primarily designed for use in connecting thetwo ends of a binding wire forming part of a wire-bound box.

The accompanying drawings illustrate my invention: Fig. 1 is aperspective view of a wire-bound boX with my device in position for use;Fig. 2, a vertical section of my improved device, on line 2-2 of Fig. 3;Fig. 3, a section on line 3-3 of Fig. 2, and Fig. i, a perspective viewof the two members of one of the locking and twisting elements.

In the drawings, indicates a casing in which is journalled a rock-shaft11 carrying a gear 12 and an operating lever 13 pro jected through thecasing. Casing 10 is provided with a fiat under face adapted to restupon the surface over which the wireends, to be twisted together, lie.

Leading into casing 10 along one of its lower corners, is a slot 14having a width equal to at least twice the diameter of the wires to betwisted, and at the inner end of this slot, in each side wall of thecasing is formed a bearing Journalled in each hearing 15 is one end of atwisting member, 16, the inner end of which is rotatively nested in alocking mem- -ber 17 one of the members having a pin 18 and the other apair of cooperating shoulders 19, 19 which permit a limited relativeangular movement for a purpose which will appear.

The twisting member 16 is provided with. a radial slot 20 having at itsinner end a width greater than one and less than two wire diameterswhile the memberl'l" is provided with a similar radial slot 21,registering with slot 20 when pin 18 lies against one of the shoulders19, and, at its inner end, having a width slightly greater than two wirediameters.

Member 17 is provided with a series of gear teeth 22. At one side of thecasing the teeth 22 of the adjacent member 17 mesh' with gear 12 whileat the other side the teeth'of that member '17 meshuwith aepinw ion 23on an idler shaft 24 having a pinion 25which meshes with gear 12,- thearrange ment being such that gear 12 will serve to simultaneously andequally rotate the two members 17 in opposite directions. The in herends of the hubs of the two members 17f are journalled in a portion 26of casing 10.

The operation is as follows The ends of the wire 27 of the package arelaid alongside of each other, the overlap being preferably substantiallythe width of casing 10 or thereabouts, and the casing is slipped intoposition with the overlapped ends lying in the slots of elements 16-17.

The first movement of lever 13 advances the elements 17-17, withoutadvancement of elements 1616 and without any twisting of the wires untilslots 21-21 are swung out of registry with their companion slots 20, 20,thereby locking the wires in the twister elements. Further advancementof lever 13 rotates the twister elements 16-16, through the medium ofpins 18, 18 and the forward shoulders 19, 19 and the ends of the wireare firmly twisted together.

hen lever 13 is shifted to the limit of its forward movement the slotswill be in registry with slot 14 while slots 21, 21 will be slightly inadvance and out of registry. A. slight return movement of lever 13brings slots 21, 21 back into registry with slots 20, 21 and 14, withoutdisturbing elements 16, 16 or the twisted portions of the wire,whereupon the casing 10 and its contained parts may be withdrawn.

I claim as my invention '1. A twister comprising a main body having atransverse bore near one corner with an inclined passageway leading fromthe adjacent corner into said bore, a pair of rotatable laterallyslotted aligned twister elements, rotatably mounted in said bore, arotatable, laterally slotted locking element aligned with each of thetwister elements also mounted in said bore, interengaging parts betweeneach locking element and its twister element permitting limited rotativemovement of the locking element relative to its twister element andsubsequent concurrent rotative movement, the slot of each twisterelement being throughout less than two wire-diameters wide and the slotsof each locking element being at least two Wire-diameters wide, andmeans journaled in the main body for simultaneously rotatingthe lockingelements and twisting elements in opposite directions.

2. A twister comprising a pair of rotatable radially slotted alinedtwister elements, a rotatable radially slottedlocking element alinedwith each of the twister elements, iiiterengaging parts between eachlocking element and its twister element permitting limited rotativ'emovement of the locking element relative to its twisting element andsubsequent concurrent rotative movement, the slot of each twisterelement being throughout less than two wire-diameters wide and the slotsof each locking element being at least two wire diameters wide, and

means for simultaneously rotating the look ing elements in oppositedirections.

3. In a wire twisting device, a rotative twister element havingthroughout a radial slot having a Width less than two Wire diameters, analined rotative locking element having a radial slot having a width ofat least two wire-diameters, interengaging parts 011 said two memberspermitting only limited relative rotation, and means by which a rotativedriving force-may be applied to the locking element.

In witness whereof, I have hereunto set my hand at Indianapolis,Indiana, this 9th day of December, A. D. one thousandninehundred andtwenty-two.

JASON H. GREENSTREET.
